Are you planning to pursue studies or an internship in Thailand? In this guide, you’ll find everything you need to know about the education visa for Thailand, the required documents, the type of visa depending on your situation, and the new mandatory TDAC form for all visitors entering Thailand.
1. The Education Visa for Thailand
To study in Thailand, you need the education visa, officially known as the Non-Immigrant ED Visa. This visa is required whether you are joining a university, enrolling in a Thai language school, or studying at an international school.
University Exchange Program
If you’re part of a university exchange, you’ll need:
- An acceptance letter from your university
- A valid student card or certificate of enrollment
Thai Language Studies
You must enroll in a school recognized by the Thai Ministry of Education and attend at least 25 hours of classes per week. Before applying, make sure the school meets these criteria.
Enrolling in a Thai Institution Independently
You must present:
- An official admission letter from the school or university
- A copy of the ID card of the person who signed the letter, marked as a certified true copy
2. Required Documents for All Students
You must submit your visa application at the Royal Thai Embassy in your country:
- Passport (valid for at least 6 months)
- Completed visa application form
- One color ID photo
- Official letter of acceptance
- Class schedule
- Proof of financial resources (minimum €20,000 in savings)
- 70 EUR in cash (visa fee)
The education visa for Thailand is initially granted for 90 days. You must apply for an extension at a local Thai immigration office before expiry. The first extension requires:
- A confirmation letter from your school proving your attendance
- Updated financial proof showing you can support yourself without employment
New Rule (May 2025): All foreign visitors, including students, must fill out the Thailand Digital Arrival Card (TDAC) within 3 days before entering the country. This replaces the old paper TM6 form.
